To Describe: Two techniques to measure the pH of a solution.
Explanation of Solution
Introduction:The pH of a solution determines how acidic or basic the solution is.
The pH of a solution is a measure of the concentration of
If pH of a solution is less than 7, the solution is described as acidic, that is, concentration of
If pH of a solution is equal to 7, the solution is neutral, that is, concentration of
If pH is more than 7, the solution is basic, that is, concentration of
The pH of a solution can be determined using universal indicator paper. A universal indicator is a mixture of organic dyes, which gives different colors with solutions of different with solutions of different pH values. The final color of the paper is matched with a chart to determine the pH.
The pH of a solution can also be determined using an instrument called the pH meter. The meter consists of two electrodes, a glass electrode and a reference electrode. The meter is operated by immersing the electrodes in the test solution and reading the voltage difference generated between the two electrodes.
A pH meter comes handy in testing the pH of soils and streams.
Conclusion:The pH of a solution can be measured using universal indicator paper or a pH meter.
